About Collet 

An external collet is a sleeve with a (normally) cylindrical inner surface and a conical outer surface.

The collet can be squeezed against a matching taper such that its inner surface contracts to a slightly smaller diameter, squeezing the tool or workpiece whose secure holding is desired.

Most often this is achieved with a spring collet, made of spring steel, with one or more kerf cuts along its length to allow it to expand and contract.

An alternative collet design is one that has several tapered steel blocks (essentially tapered gauge blocks) held in circular position (like the points of a star, or indeed the jaws of a jawed chuck) by a flexible binding medium (typically synthetic or natural rubber).

Specification of TPC Tap Collet:

1.Safety quick change.

2.Torque type wire tapping chuck,can prevent broken in the tapping
